HVAC & Duct Speech Privacy
Shared HVAC ducts, plenums, and penetrations can carry intelligible speech between rooms, a flanking path that can be exploited deliberately or leak casually.
Solutions
How we solve it
Diagnose duct and plenum flanking, then harden the path with duct/penetration treatments and speech-privacy delivery (including duct-oriented masking where it fits) so plant rooms and shared air paths stop acting as listening corridors.
What you are dealing with
Voices carry between floors through shared ductwork. Plant rooms and risers act as listening corridors. Partition ratings look fine on paper but speech still flanks through HVAC penetrations.
Our approach
We trace duct and plenum flanking paths with measurement, then harden penetrations and apply duct-oriented masking where it fits. The goal is to stop shared air paths acting as speech highways without unnecessary plant shutdown.
What done looks like
Duct and plenum paths no longer carry intelligible speech between intended zones. Penetration treatments are documented. Masking zones align with actual air paths, not only ceiling grids.
